It doesn’t make as high a difference as many people think. I am currently running 46 and 48 tooth Shimano Hollowtech II on two road bikes with unmodified road front derailers. Neither is “made” for that small chainring but both function just fine. Shifts are smooth and crisp. I have no issues with the derailer being too long and hitting the frame.
